Definitions
- the invention relates to a method for false twist of filament yarn, the filament yarn being transported through a continuous twist channel of a false twist nozzle that is free on the inlet and outlet side, and a multi-part false twist nozzle for producing a false twist textured filament yarn with a continuous twist channel that is free on the inlet and outlet side and an insert with tangential compressed air entry into the yarn channel.
- the false twist mostly has the function of imposing a strong mechanical twist on the filament for only a short time, which in a heating and cooling stage directly in front thermally changes the structure of the filament Filêts is fixed, so that after the twist ceases, a crimping effect on the yarn and better cohesion results for the filament yarn.
- the typical characteristic of the false twist is the free guidance of the filament yarn into the false twist nozzle and out of the false twist nozzle.
- the W098 / 33964 shows another special application for the simultaneous stretch texturing of partially drawn yarn and the use of a multi-part, real false twist nozzle.
- the inventor had discovered that, contrary to all previous expert opinions, a work area or a work window can be used with a supply pressure of the compressed air between about 14 and 80 bar.
- a special nozzle concept was developed which, despite the relatively high pressure due to miniaturization of the nozzle body, hardly uses more air than an older type nozzle with a much lower pressure of the supply air.
- Single-stage compressed air generators operate in a pressure range up to approx. 1 2 bar. This means that the pressure range above 12 bar requires multi-stage compression, which limits the range of use for swirl generation according to the solution of W098 / 33964 to companies with corresponding multi-stage compressed air systems.
- the invention was based on the object of developing an economically producible false twist nozzle concept, in particular with a closed yarn channel, which allows the specific advantages of air use, above all instead of the previously mechanically applied false twist generation on the yarn and possibly in other applications, eg can also be used for the medium pressure range.
- the method according to the invention is characterized in that the compressed air in the false twist nozzle is first guided in the direction or along the yarn transport path, preferably in parallel and then tangentially into the yarn channel, so that the false twist on the free-running filament yarn is generated by and by a swirl flow in the yarn channel a previous heat treatment of the false twist effect can be thermally fixed and a crimped yarn can thereby be produced.
- the false twist nozzle according to the invention is characterized in that it has at least one swirl insert plate with a compressed air hole running preferably parallel to the yarn channel axis and a continuous piece of yarn channel, furthermore a tangential channel opening into the yarn channel piece and at least one further element, each with the Twist insert plate has a corresponding thread channel piece or a compressed air hole.
- the twist movement can be used for various purposes, be it for better bonding of the filaments of a single yarn or for connecting several yarns. Laboratory tests confirmed that the Function of the previous mechanical swirl generator is achievable, so that the corresponding use in practice is possible for the first time.
- the new invention is based on the knowledge that the sensitive zone for optimal function is largely determined by two extremely small nozzle sections. These are:
- the swirl flow is a dominant circular flow and is therefore not disturbed by the circular transitions.
- the core piece namely the tangential or acceleration channel and the associated yarn channel piece, can now be designed more freely and can be produced in much higher quality and accuracy than was previously the case.
- the shaping of an exposed plate can be done by a variety of manufacturing techniques, such as Eroding or laser technology.
- the false twist and the immediately preceding thermal fixation are preferably carried out between two supply units LW1 and LW2.
- the new invention allows a whole range of design options, which can be implemented particularly easily with eroding technology. Above all, this applies to detailed shapes that were previously not possible to produce. For this purpose, reference is made to claims 2 to 9 and 8 to 25.
- the new solution should not be limited in terms of yarn titer, even if the largest possible area of use is currently assumed in the medium titer range. As Rule of thumb applies: fine titer, fine drilling, rough titer, rough drilling. In practice, however, there is no definable boundary between the two areas.
- fine titer, fine drilling, rough titer, rough drilling In practice, however, there is no definable boundary between the two areas.
- the production of completely new duct shapes that can be optimized for the particular use opens up, which were previously not possible.
- W098 / 33964 shows in FIGS. 6a to 6d a first approach in the direction of the new solution.
- the main idea in the older application was the miniaturization of the entire air treatment nozzle and, accordingly, all the air channels in order to keep air consumption low at the pressure of over 14 bar, which is unusually high in textile practice.
- a number of very thin slices were found to be the solution.
- the duct design was still based on the traditional concept of "air supply drilling", that is to say with purely radial air supply, in the plane of the tangential or transverse duct.
- Corresponding discs a few millimeters in diameter and e.g. A thickness of 0.2 millimeters belongs more in the watchmaking industry with millions of pieces and corresponding robot aids. In any case, the much lower numbers of air nozzles for a correspondingly small market niche in the textile area would question economic production in the introductory phase. However, as is well known, the introductory phase is the decisive period that decides whether a new product is successful or not. In contrast, the new invention opens up completely new possibilities, as will now be explained on the basis of some very advantageous embodiments.
- the swirl insert plate particularly preferably has at least two channel openings, for the air supply channel on the one hand and the yarn channel on the other hand, which are connected to generate the swirl flow with the tangential channel, designed as a short air acceleration channel in the manner of a functional pattern.
- the twist insert plate gets a special, glasses-like character from the two bores and the relatively narrow connection through the air acceleration channel, which is referred to as a functional model.
- the concept of the functional pattern takes on a descriptive meaning in the sense of a printed pattern on textiles in the case of two, but particularly in the case of a large number of identical patterns arranged next to one another.
- the new solution results in several levels for the concrete implementation in practice.
- a first level concerns the tangential channel.
- the tangential channel preferably has a length in the region of the diameter of the two bores for the yarn channel piece and the compressed air bore.
- the tangential channel is preferably designed in the manner of a Laval nozzle for a sound flow or for a supersonic flow with the typical expansion in the exit region of the acceleration channel into the yarn channel. From a structural point of view, the term tangential channel is somewhat relativized from the point of view of the supersonic nozzle. According to the new solution, tangential refers to the effect, namely the generation of an optimal or maximum swirl flow. There is a large variation in the mouth area of the Laval form, as will be shown with examples.
- the air acceleration duct for the air supply from the compressed air bore in the direction of the yarn duct is preferably designed to be narrowed.
- the channel openings have a preferably uniform shape with the highest surface quality over the entire plate thickness.
- the corresponding channel openings in the swirl insert plate are cylindrical, the air acceleration channel connecting the two channel openings over the entire plate thickness.
- a third level concerns the division of the swirl insert plate.
- the division into two or more pieces opens up new degrees of freedom for a wide variety of applications.
- the divided swirl insert plate creates, at least theoretically, the prerequisite for exposing the entire yarn channel for threading, but primarily for the production of any and also complex shapes, especially miniaturized shapes.
- the division can be designed in such a way that the functional pattern is only formed by assembling two or more parts of the swirl insert plate.
- the cut for the division can be made, for example, through the two channel openings for the yarn channel and above all also through the air acceleration channel and the air supply. It is very interesting. to divide the swirl insert plate in such a way that mutual anchoring points arise in such a way that the precision of the flow-active parts in the assembled state is forcibly ensured by the anchoring points.
- a swirl insert plate in parallel arrangement has two or more yarn channels, each with its own air supply or several functional patterns, etc.
- Any number of yarn channels on a twist insert plate with the smallest possible pitch e.g. on a common center line.
- the area of the channel openings is expediently provided for a separation point for a two or more parts.
- kits consists of at least one swirl insert plate and at least one further element which is designed as a support block and has the air supply and a connection for a compressed air connection.
- the kit preferably has additional elements which are designed as insert plates without an air acceleration channel, but with at least two channel openings for the air supply and the yarn channel, the corresponding channel openings forming a uniform flow channel in the assembled state.
- At least one twist insert plate for S-twist and at least one twist insert plate for Z-twist, each with a separate air supply, or a single twist insert plate with the two corresponding opposite functional patterns can be combined for parallel guidance of two threads.
- a kit can also have insert spacers for selecting the distance, at least between two swirl action points.
- the possibility of free choice with regard to the division proves to be very advantageous.
- False twist nozzles have the enormous advantage that, in the case of parallel guidance of threads, the pitch and, accordingly, the space required is only millimeters or centimeters instead of decimeters. This makes it possible to realize significantly more compact parallel runs, shorten the process zone in the area of the previous spindles and, as a great advantage, the corresponding construction of more compact machines.

- Figure 1 b is a simplified control scheme for the treatment of individual threads.
- Figure 1 a is to be understood more schematically. It shows an example of a change control or alternately false twist, either for an S-twist or a Z-twist.
- the air swirl nozzle 6 has two compressed air connections, 9 and 1 3, and correspondingly two air feeds, 1 1 and 1 2, via which compressed air can be fed alternately.
- a switching valve 15 is switched by a control ST in a predetermined or preselectable rhythm, in seconds or milliseconds, and gives compressed air to one or the other side, so that an S or Z twist on the yarn can currently be generated.
- Figure 1b shows an application to single threads, e.g. also for disposition according to Figures 2b, 2c, 2d.
- the sensor can detect the tension or any qualitative parameter, also e.g. the swirl effect.
- FIG. 2a is an example of the prior art with four thread runs and the corresponding number of mechanical spindles 50, which each generate the desired S or Z twist.
- the length of the process zones VMD which is required by the mechanical swirl generator 50 or its structural dimensions, is characteristic.
- the first heater has a predetermined division T1.
- the mechanical swirl generators require a larger division T2.
- the change in the molecular orientation produced by the treatment is shown on the right in FIG. 2d, on the one hand as an outer geometric configuration of the yarn thread and on the other hand as an inner orientation of the molecules.
- the result of the known false twist texturing is a crimp yarn (Gk syndromes), due to a corresponding permanent internal structural change.
- FIGS. 3a and 3b show the core components of a false twist nozzle according to the new solution.
- FIGS. 3a and 3b show a preferably continuous operation, ie the compressed air supply is never switched off during operation.
- the structural design can be designed, for example, according to FIG. 10c.
- One possible practical application is folding, for example according to FIG. 10c.
- the air pressure can be 14 to 40 bar.
- the heart of the false twist nozzle is a swirl insert plate 1 with the characteristic dimensions of length L, height H and thickness D. According to the current state of development, the height ranges between approximately 0.5 cm and 2 cm, the length from 2 to 10 cm and up to any length for a large number of parallel yarn runs.
- the thickness of the plate can be between 0.5 millimeters and one centimeter, preferably between about 1 mm and 5 mm.
- a typical plate character results from the preferred dimensions.
- a functional pattern 2 consisting of a yarn duct piece 3 ', an air supply 4 and an acceleration duct 5.
- the entire air swirl nozzle 6 is drawn in the manner of an exploded view, with the individual components moved apart.

- the connection means for the three parts, element 7, swirl insert plate 1 and the end plate 14 are not shown.
- the connection can be made by screws, clamps, etc. and must withstand the pressure forces and ensure tightness.
- Figure 3b is designed analogously, with the exception of the direction of the wire. Depending on the direction through which the yarn runs, there is an S-twist in FIG. 3a and a Z-twist in FIG. 3b, or vice versa with the yarn running in the opposite direction.
- FIG. 3b has another compressed air connection 13, as indicated by arrow 12. Accordingly, the air supply hole 8 'connects the air supply 4'.
- FIG. 3c represents a possible combination of FIGS. 3a and 3b.
- FIG. 3c corresponds to the solution according to FIG. 1a and is designed for alternating operation. Only either an S or a Z twist is generated.
- the compressed air can be 2 to 25 bar. Tests with 14 to 22 bar gave consistently very good results. If very short changeover times are required, for example in the millisecond range, a higher pressure of 30 to 40 bar can be disadvantageous depending on the valve design due to the inertia of the system.
- the two functional patterns are aligned with the same yarn channel 3, but are switched in succession.
- a changeover valve 15 which supplies the compressed air in a time-controlled manner to one side or the other. So that the compressed air is fed to the swirl insert plate 1, the swirl insert plate 1 x additionally has one Air supply hole 4 X , which feeds the compressed air from the compressed air connection 9 to the air supply 4.
- the change in the swirl flow from S to Z swirl and vice versa can be controlled in any cycle sequence and the individual swirl type as long as is required by the specific application.
- the changeover can even take place in the range of milliseconds with miniaturized diaphragm valves.
- two further insert spacers 17 and 18 are indicated. This means that regardless of the thickness D of the twist insert plates, the yarn channel length can be varied locally and as viewed over the entire air twist nozzle.
- Figures 4a to 4f show a number of different functional models for swirl insert plates.
- LD is the diameter of the air supply 4 and Gd the diameter of the yarn channel 3 in the area of the yarn channel pieces 3 '.
- the yarn channel 3 has, seen in cross section, advantageously a circular shape or at least approximately a circular shape.
- the cross-sectional shape of the air supply 4, however, can be chosen arbitrarily and even rectangular.
- A denotes the entry zone into the acceleration channel 5 and C denotes the exit zone from the acceleration channel 5 or the entry into the yarn channel piece 3 ′.
- BL is the length of the acceleration channel and B is the channel width seen in the image plane.
- the acceleration channel 5 has a increasing, continuously rectangular cross-sectional area, which results from thickness D times width B.
- FIGS. 4c, 4d, 4e and 4f show solutions with an enlarged outlet zone for a supersonic flow.
- the primary objective 4c shows a section IM - III directly above it.This is to show that, depending on the selected design optimization, only a part of the cross section of the twist insert plate or the Plate thickness D can be used for the formation of the acceleration channel.
- FIG. 5a schematically shows the generation of an S or Z twist on the same yarn by appropriately controlling the supply of compressed air.
- the two twist directions are each shown on a swirl insert plate and in FIG. 5e with two threads 10 running in parallel.
- FIG. 5d shows the arbitrary multiplication of the functional pattern for a corresponding number of threads running in parallel.
- the swirl direction shown in Figure 5e is always the same. However, this can also be changed as required.

- the upper plate part 30 has a foot 32 as a positive form and the lower plate part 31 has a foot 33 as a negative form. Both feet 32, 33 not only fit exactly into one another (FIG. 7b). They also ensure the corresponding functional model.
- the three flow forms only form after the joining: the yarn duct piece 3 ', the acceleration duct 5 and the air supply 4.
- FIG. 7b shows a swirl insert plate with an upper plate part 30 and a lower plate part 31 in the installed state. Since the swirl insert plate must be made of a particularly wear-resistant material, an entire housing shape is made of steel and, if necessary, several swirl insert plates T1, T2, etc. are used. According to FIG.
